Python–张量流。DeviceSpec.from_string()
原文:https://www . geesforgeks . org/python-tensorflow-device spec-from _ string/
TensorFlow 是谷歌设计的开源 Python 库，用于开发机器学习模型和深度学习神经网络。
from_string 用于从字符串生成 DeviceSpec。
语法:张量流。DeviceSpec.from_string(规格)
参数:
- 规格:是格式/作业:/副本:/任务:/设备:CPU:或/作业:/副本:/任务:/设备:GPU 的字符串，所有条目都是可选的。
返回:返回字符串生成的 DeviceSpec 对象。
例 1:
Python 3
# Importing the library
import tensorflow as tf
# Formatting the string
spec = '/job:gfg / replica:1 / task:2'
# Initializing Device Specification
device_spec = tf.DeviceSpec.from_string(spec)
# Printing the DeviceSpec object
print('Device Spec: ', device_spec)
输出:
Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fadb9428168>
例 2:
Python 3
# Importing the library
import tensorflow as tf
# Formatting the string
spec = '/job:gfg / replica:2 / task:3'
# Initializing Device Specification
device_spec = tf.DeviceSpec.from_string(spec)
# Printing the DeviceSpec object
print('Device Spec: ', device_spec)
输出:
Device Spec: <tensorflow.python.framework.device_spec.DeviceSpecV2 object at 0x7fadb9428228>
